duplicateRelatedRecords property in relations from SM

Hi all!

Today we realized that exists a property duplicateRelatedRecords in relations created/got with solutionModel.

However it doesn’t exist in design time:

Is this property used? Can we set and use it? Which is the expected behaviour?

Thanks in advance!

thats a deprecated property that is not used.
I will remove it from JSRelation completely to get rid of the confusion
